I have to agree. Wordplay messed up in the middle of a book and I haven't been able to get it to show that book again. Aldiko reads the exact same file without a problem. NOt to mention that I can't get Calibre (XP) to communicate with Wordplay on the Droid.

I wish both of them would indicate progress in the whole book and not just the chapter but that's for another forum I guess.
